The SDL forums have moved to discourse.libsdl.org.
This is just a read-only archive of the previous forums, to keep old links working.

Hi,

I enclose a small patch that allows the SDL version of the NeHe
tutorials (from http://www.libsdl.org/opengl/index.php) to compile on
Cygwin without fuss. Since it patches configure.in, it will obviously be
necessary to run autogen.sh after application.

I trust that this is an appropriate place to send the patch. If not,
please accept my apologies.

Dan
